Detlef Wiedeke and Michael Scholz are currently Systems In Blue, with Rolf Köhler and Olaf Senkbeil being former members. This is a German group that continues with the sound of eurodisco from the 80's with a modern touch. They used to work with Dieter Bohlen on bands like Modern Talking and Blue System. http://en.wikipedia.org/wiki/Systems_in_Blue http://www.systems-in-blue.de/
